                                             technical quality items. CHWs often lacked essential supplies, and only six percent
                                             carried all four of the CHW job aids and tools specified in the national guidelines for
                                             maternal health at community level. However, CHWs completed an average of 7.3
                                             (SD = 1.1) of the 8 communication quality items, and most PNC clients (88%) report-
                                             ed being satisfied during follow-up interviews. Higher technical quality scores were as-
                                             sociated with older mothers, better communication, longer visit duration, and CHWs
                                             who carried at least three job tools. CHWs expressed a strong sense of responsibility
                                             for care of their clients, while clients underscored how CHWs were trusted to main-

                                               services to women during the immediate postnatal period is necessary and has the potential to reduce mater-
                                               nal and infant illness and death [12]. However, the quality of care that CHWs provide – particularly during
                                               the postnatal period – is often poorly measured. There is need to better understand the nature and quality of
                                               care that CHWs provide and how they might be better supported [13]. Quality of care encompasses provi-
                                               sion of technical quality and experience of care [14], both of which can also be used to understand quality of
                                               community-based care.
                                               Assessing the quality of interactions between CHWs and community members is important in understanding
                                               how the services that CHWs provide affect the health outcomes of community members. Client satisfaction
                                               with services is often used as a proxy measure for quality of care provided by CHWs; however, as programs
                                               scale up, measuring the technical quality of the services delivered becomes critical [15]. Prior studies have
                                               identified challenges in assessing the impact of CHW programs on service quality, due, in part, to design lim-
                                               itations [16,17] and lack of standardized quality assessment metrics [18]. This paper reports on quality of care
                                               measured by process and experience of maternal and young infants (under 60 days old) care services provid-

                                               Community health services in Kenya
                                               Although Kenya has increased efforts towards achieving the Sustainable Development Goals (SDG) targets of less
                                               than 70 maternal deaths per 100 000 live-births and 12 neonatal deaths per 1000 live births by 2030 [19,20],
                                               the number of deaths remain relatively high [21]. One strategy being championed to reduce maternal and neo-
                                               natal mortality is to increase access to services at lower levels of the health system, especially at the community
                                               level [22]. Kenya has a four-tier health system structure with the vision of strengthening and re-emphasizing
                                               the focus on a primary health care (PHC) network. Community health services (CHS) are articulated as first-ti-
                                               er health services in the Ministry of Health (MoH) policies [22-24], and are embedded within the PHC concept
                                               [25]. The first tier is represented by Community health units (CHUs), each of which serves a catchment popu-
                                               lation of 5000 people and is staffed by 10 volunteer CHWs (referred to in Kenya as community health volun-
                                               teers – CHVs) and supervised by a community health extension worker (CHEW). CHEWs are qualified indi-
                                               viduals that are employed by the formal health system to provide training and technical support to CHVs. Each
                                               CHEW supports approximately 25 CHVs. The CHVs are chosen by their community to provide home-based
                                               care and counselling services. Through their activities, they create demand for formal clinical services and link
                                               clients to second-tier PHC services at dispensaries and health centers [25]. As CHVs support early identifica-
                                               tion and treatment of diseases and are directly aware of the needs of their community, they are often perceived
                                               as role models and recognized as champions for health-related matters. Evidence suggests that CHS in Kenya
                                               increases attendance of at least four antenatal care visits, deliveries by skilled birth attendants, intermittent pre-

                                               In this context, we examined the technical and experiential quality of PNC for women and their babies provid-
                                               ed by CHVs in Kenya using observations of home visits and follow up surveys. We describe data on the scope
                                               of PNC care provided by CHWs to women and infants and document underlying drivers of quality care. We
                                               compare the expected practices using national guidelines for providing maternal and infant health services at
                                               community level [28].

                     The study was conducted in rural settings in Kilifi (coastal) and Bungoma (western) Counties. Both counties
                     reflect a range of commonly observed barriers to care, including geographical access constraints and cultural
                     vulnerabilities. Kilifi has a neonatal mortality rate of 26 deaths per 1000 live births, a skilled delivery rate of
                     52.3%, an under-five mortality rate of 141 deaths per 1000 live births, and a maternal mortality ratio of 540
                     deaths per 100 000 live births. Bungoma has a neonatal mortality rate of 33 deaths per 1000 live births, a skilled
                     delivery rate of 44%, an under-five mortality rate of 145 deaths per 1000 live births, and a maternal mortality
                     ratio of 360 deaths per 100 000 live births [29]. Kilifi and Bungoma Counties were purposefully selected in
                     collaboration with County Health Management Teams to include a functional CHS where CHVs conduct rou-
                     tine visits, collect data, and receive some form of incentives. Additionally, the selected sites had several collab-
                     orative projects between non-governmental organizations (NGOs) and the government being implemented to
                     strengthen local CHS through capacity building and improve access to health information.

                     PNC home visit observations
                     From 29 July to 23 August 2019, we shadowed 68 CHVs – 32 in Kilifi County and 38 in Bungoma County
                     – as they conducted PNC home visits with postnatal women whose infants were less than 60 days old. CHVs
                     were linked to 12 facilities representing different tiers of the health system (eg, referral hospital/one sub-coun-
                     ty hospitals, health centers, dispensaries); three quarters were female. We observed between 1-3 PNC home
                     visits with each CHV. During observations, trained research assistants with social science backgrounds com-
                     pleted an observation guide without intervening during the home visit.

                     the national CHV Manual [28] and are routinely completed by CHVs during a PNC visit. These items com-
                     prise four domains: infant health warning signs, maternal health warning signs, essential newborn care, and
                     breastfeeding. Observers directly assessed whether CHVs completed these 25 items during PNC home visits.
                     The observations also assessed CHV’s communication with their clients, whether follow-up actions were tak-
                     en when an infant was identified as unwell, and whether CHVs were properly equipped with four essential
                     job tools: referral slips for follow-up care, a visit schedule register, the CHV household handbook, and a set
                     of community health job aids.

                     PNC client follow-up survey
                     Within two weeks of completing each observation, we conducted follow-up surveys with the observed PNC
                     clients. During the follow-up interviews, we collected basic demographic information and assessed the client’s
                     experience of the observed CHV visit, including the four PNC domains and their communication with the
                     CHV. Interviewers asked women about their perceptions of the 25 health checks assessed during the observa-
                     tions and asked a series of communication quality items about the social interaction and attitudinal aspects of
                     care. Interviewers also asked women about their satisfaction with the care they received from the CHV using
                     a Likert-scaled item with four ordinal responses ranging from very dissatisfied to very satisfied.

                     Qualitative interviews
                     To better understand the contextual factors that influence CHVs ability to plan and conduct PNC visits, we
                     held IDIs with 12 of the CHVs who were observed during a PNC visit and eight of the CHEWs who super-
                     vise them. We also conducted two FGDs in each county (ntotal = 4), with a total of 29 postnatal women whose
                     CHV home visits were observed for this study. Trained qualitative interviewers facilitated IDIs and FGDs us-
                     ing pre-developed interview guides.

                     Analysis
                     We present cross-sectional data from the technical and communication quality checklists as observed during
                     PNC home visits. Specifically, we examined the proportion of visits at which each item in the checklists were
                     completed and produced summary scores for each domain. As some checklist domain scores might improve

                                                We observed a total of 166 PNC home visits (Kilifi: n = 82; Bungoma: n = 84) that lasted an average of 23 min-
                                                utes, with an average of 2.2 PNC visits per CHV (standard deviation (SD) = 0.73; range = 1-3 visits). Follow-up
                                                interviews were completed with 148 (Kilifi: n = 70; Bungoma: n = 78) of the observed clients. According to
                                                the MoH guidelines, postnatal women and their infants are supposed to receive visits at least seven times after

                     instance, many of the items in the neonatal care domain, which are most relevant immediately after birth, were
                     assessed more frequently during the third or greater contact than at the first.
                     CHVs did not confirm whether the child was unwell at one-third of observed visits (data not shown, 37.8%).
                     Among the 92 visits where the CHV did confirm the child’s wellness, 11 (12%) subsequently checked the child
                     for additional symptoms, and seven referred a child for additional health services; the most common symp-
                     toms were inability to pass urine or stool (n = 5) and restlessness (n = 3).
                     Qualitative data from women who received PNC from CHVs reinforce the emphasis on breastfeeding as a ma-
                     jor area of focus (Table 3); not only do CHVs explain in detail how to continue this practice, but they are able
                     to situate it within the broader context of a woman’s own nutritional status and life circumstances. Despite the

                     Qualitatively, most CHVs felt that they were able to communicate freely and effectively with postnatal wom-
                     en. CHVs described developing a trusting CHV-client relationship where a client feels secure as critically im-
                     portant in empowering women to be active participants in their care. They concurred that first-time mothers
                     are counselled differently than others, with greater emphasis on danger signs. The CHVs also mentioned the

                                                                                                                                                               RESEARCH THEME 3:
                     importance of health facility nurses reinforcing the material that is initially presented by the CHVs during rou-
                     tine home visits.

                                                                                                                                                               COMMUNITY
                              “When a [CHV] explains to them and gives good counsel, they understand and follow whatever you tell
                              them… [also] there are no challenges when [some]one gets pregnant… they remember when someone
                              [else] was [pregnant], and [the CHV] told me this and that.” – IDI, CHV
                              “At the community, it happens during the household visits… That is when we sit down with the mother
                              and talk to her; if she is pregnant you talk to her about the importance of going to the clinic, the impor-
                              tance of delivering at a health facility and eating a balanced diet. If she is a mother of a young child, you
                              also show her how to breastfeed the baby well, to use family planning and all that. So, it can either be
                              in a group or it can be done one on one.” – IDI, CHEW
                     Additionally, CHVs described feeling responsible for ensuring that their clients were provided with necessary
                     facility-based services by personally bringing them to the facility or supporting their clients at personal expense.
                              “If you see that she is completely unable to afford anything, as a CHV, it is your responsibility to also
                              help them by either bringing them to the hospital or providing for them money for the hospital and the
                              items required if you can afford to.” – IDI, CHV
                     Experiential quality of interactions as described by follow-up survey findings (data not shown) suggest that
                     most clients (87.8%) were satisfied with the care they received from the CHV. Only 12.2% reported being
                     dissatisfied (7.4%; n = 11) or very dissatisfied (4.7%; n = 7). Satisfaction appeared to improve as contacts in-
                     creased. Nearly one quarter of participants who were observed during a first contact reported dissatisfaction,
                     while none of the participants who were observed during later contacts (three or more) reported being dissat-
                     isfied with the care received from the CHV. This trend, however, was only marginally significant (P = 0.052).
                     Among the 18 women who reported being dissatisfied, seven cited the CHV taking insufficient time with her
                     as the main reason they were not satisfied, and five said it was because the CHV repeated themselves or did
                     not teach them anything new. One respondent said she was dissatisfied due to the expectation of being hospi-
                     table to the CHV while she was also caring for her newborn.
                     Qualitatively, clients describing factors contributing to their satisfaction or dissatisfaction with CHV care fo-
                     cused less on prescribed PNC wellness checks (technical quality) and felt that communication quality and
                     trusting interactions with CHVs were more important. In the PNC context, trust manifests uniquely in relation
                     to the reliable information and support a CHV affords both mother and infant over the course of multiple vis-
                     its. Clients associate the affirming, positive and trusting relationships with CHVs in their ability to give advice
                     in an approachable way, explain and translate doctors’ and nurses’ messages, refer and accompany clients to
                     facility-based care, and follow up to ensure positive sustained outcomes (Table 5). Several clients drew on the
                     notion of confidentiality to report feeling they could speak freely with their CHV and would trust them with
                     handling personal issues discretely and effectively (handling sensitive topics like postnatal family planning),
                     while others were more reluctant to share sensitive information with CHVs who they perceived as untrust-
                     worthy. Clients also described some factors, such as negative quality of care or poor health outcomes at a re-
                     ferral facility (untimely or incomplete response or infant death), that were beyond the control of the individual
                     CHV, but nevertheless contributed to sense of ‘broken’ trust (Table 5).

                     Confounders and context
                     At the start of a PNC home visit, study observers first assessed whether the CHV was equipped with four es-
                     sential job tools: referral slips for follow-up care, a visit schedule register, the CHV household handbook, and
                     a set of job aids. In only 6.1% of visits did the CHV carry all four tools. The proportion who either carried all
                     four tools, or none did not vary significantly by visit number. Referral slips and the CHVs’ visit schedule regis-
                     ters were available at half (50.0% and 51.4%, respectively) of observed visits. CHVs carried job aids to 26.4%
                     of visits and had their handbook available at 18.2% of visits.
                     Qualitatively, CHVs described using their schedule register to track their household visits, to make monthly
                     PNC home visit plans, and identify the topics they will discuss during upcoming visits.

                     DISCUSSION
                     CHVs are essential community level providers who can deliver accurate and timely health information and

                                                                                                                                                       COMMUNITY
                     counselling services to women during the immediate and extended postnatal period if they are equipped ade-
                     quately. This study demonstrates gaps in the technical quality of CHV practices (completion of health checks,
                     targeting the content of the contact to postnatal women and infant’s age, use of tools, and enabling supplies).
                     However, these gaps illustrate the importance of considering and building upon the non-technical or experi-
                     ential quality elements related to strong CHV-client relationships.
                     Technical quality gaps reveal that CHVs completed only one quarter of the 25 prescribed PNC health checks,
                     averaging 6.4 (95% CI: 5.7-7.1) during a home visit. These figures are consistent with similar PNC visits per-
                     formed by health extension workers in northern Ethiopia [30]. However, when we examine checklist items
                     individually, we find that the completion of any one item at a given point in time rarely follows a systematic
                     pattern. To this end, the observation data suggests that there are no significant relationships between summa-
                     ry scores for the other domains – or for the total score for the checklist – and visit number. CHVs are expect-
                     ed to make home visits in the intermediate and extended postnatal period (as per national guidelines) [28].
                     Many of the 25 items included in the checklist were applicable at specific time points in the postnatal period
                     and some only during the period immediately (48-76 hours) following childbirth (eg, essential newborn care
                     domain, breastfeeding items including suckling and colostrum, some maternal danger signs). However, our
                     observations indicate that many health checks, when they were completed, were performed with little con-
                     sideration given to timing or appropriateness of messaging. CHVs were still discussing essential newborn care
                     with a fifth of women whose infants were over 28 days old.
                     While qualitative data captured how CHVs educated first time mothers on infant danger signs, observations
                     suggest that CHVs may be less systematic in targeting the information they present to their clients. Despite
                     their lack of targeted counselling, CHV performance on the breastfeeding domain appears to resonate with the
                     broader literature on their effectiveness in promoting mother-performed strategies such as skin to skin care
                     and exclusive breastfeeding [17].
                     Three reasons may explain these observations. The first reason is that CHVs residential proximity and famil-
                     iarity with the infants and women may lead them to prioritize components that they consider important (eg,
                     breastfeeding) over others (eg, checking for danger signs among either mothers or infants). It is possible that
                     CHVs intentionally skipped these items upon seeing that both mother and child were healthy-looking or cov-
                     ered these items at previous contacts. Second, as reflected in the qualitative data and global evidence of CHW
                     programs, CHVs cover large catchment areas and experience increasing responsibility, making it hard to spend
                     more time with the mothers [31,32]. These challenges, coupled with poor support for planning and efficiency,
                     contribute to job stress and high attrition rates in CHW programs globally [31,32]. Finally, the current CHS
                     structural norms in Kenya regard CHVs primarily as health service demand generators – namely community
                     mobilizers that increase awareness and facilitate people’s access to medical facilities [33], rather than health
                     workers that require supportive supervision and continuous updates of their skills. CHVs felt responsible for
                     generating demand and ensuring that their clients completed referrals–an approach reinforced when CHVs
                     supported their clients’ transit at personal expense. These findings are consistent with research across country
                     settings advocating for role clarity of and increased support of CHWs as linked to improving equity, quality

                     Aggregate technical quality scores appear to be influenced by the availability of job aids, illustrating the need
                     to ensure that CHVs are equipped with essential supplies tools when conducting home visits. While technical
                     quality gaps in CHVs’ performance of PNC checks are likely attributable to a range of factors, our data suggest
                     that failure to bring essential supplies to PNC home visits (Table 4) was a common occurrence and is like-
                     ly linked to low technical quality scores. CHVs most frequently carried their referral slips and visit schedule
                     registry, enabling management of their workflow and referrals, however they carried the Household Hand-
                     book and CHV job aids less frequently. These items directly support the technical quality of CHV-led activi-
                     ties, including health check prompts. We found CHVs who carried three or more tools completed significantly
                     more prescribed health checks than CHVs who lacked these items; stratified analyses by type of tool carried

                                               demonstrated that the Household Handbook and CHV job aids were principally responsible for these increas-
                                               es in observed technical quality of care. However, when these job aids were present, CHVs completed only a
                                               fraction of the items included in the checklist, limiting their ability to effectively target age-specific messages.
                                               Perhaps strategies to optimize the job aids in digital format may facilitate easy carry and use that can help tar-

                                               and further exploration of non-use may help facilitate improvements to and use of job aids. Studies suggest
                                               that simple tools can enable CHVs to plan and prioritize care, identify disparities in service delivery, and pro-
                                               mote positive maternal and infant health outcomes [36,37]. These studies demand investment in multi-day
                                               training and continuous support for CHVs to use the job-aids effectively.
                                               Our findings also showed that CHVs’ non-technical responsibilities often extended beyond the essential well-
                                               ness checks, and CHVs perform well in the quality of communication between themselves and clients. Obser-
                                               vations show that CHVs scored an average of 7.3 (92%) out of eight possible communication quality points
                                               during observed PNC home visits. Qualitative data validated this observation, as both CHVs and clients noted
                                               that experiential quality of interactions was considered positive, with minimal dissatisfaction of services. Where
                                               dissatisfaction was reported, it was most linked to clients who felt their CHV spent insufficient time with them,
                                               or to clients who felt their CHV repeated basic information or did not teach anything new during their visits.
                                               CHV’s clients respected and trusted to maintain their confidentiality accrued social capital for providing safe
                                               and reliable entry to formal health services in sensitive or personally challenging situations. Future studies
                                               should examine whether facilitated referrals improve referral completion, or how trust in CHVs’ discretion
                                               may empower women to seek care for sensitive health issues. Future efforts to build capacity of CHVs and
                                               improve technical quality should not discount the less structured responsibilities carried out by CHVs and
                                               should leverage the positive community-CHV relationships[12] that characterize experiential quality of care.
                                               Moreover, the postnatal period has long been neglected, including in health facilities in Kenya [38] where safe
                                               motherhood vouchers were available for poorer women to access postnatal services [39]. Despite some im-
                                               provements in uptake of PNC from 10% in 2003 to 51% in 2014 [29], many women who seek maternity ser-
                                               vices are not checked by any facility provider after childbirth [40]. It is therefore not surprising that postnatal
                                               women and their babies do not receive optimal care at the community level. Immediately, community health
                                               program planners should ensure job aids are always available and consider ways to tailor them to ensure that
                                               the timing of essential health checks and counseling messaging is consistent with the life stage of the infant.
                                               Furthermore, revising CHV PNC scope of work and increasing systemic supports to CHVs would improve
                                               technical quality of PNC and integrate it into the PHC network in Kenya [22].

                                               Limitations
                                               This paper has several limitations. While our study shows that measuring technical and experiential quality of
                                               care provided by CHVs is feasible, comparative work is needed to assess transferability of the PNC observa-
                                               tional checklist communication quality indicators (items and summary scores). The sample size of postnatal
                                               observations and client surveys was limited, and we recommend further testing in higher-powered studies in
                                               additional settings in Kenya and globally. As this study was only conducted in two counties in Kenya that have
                                               ongoing programs designed to support CHV-led activities, our results may over-estimate technical quality and
                                               are unlikely to be nationally generalizable. Similarly, although we tried to observe all CHVs attached to the
                                               health centers and dispensaries targeted by this study, there may be some level of self-selection bias wherein
                                               higher-performing CHVs would be more likely to agree to be observed. Again, such biases would likely lead
                                               to overestimates of technical quality during PNC visits. Given the cross-sectional nature of the study, the re-
                                               gression analysis did not consider the time-lag between which CHVs were trained on the technical module
                                               on maternal health by the MoH or the intensity of supportive supervision. This was beyond the scope of the
                                               study and would be helpful consider in future longitudinal designs.

                                               CONCLUSIONS
                                               This study identified gaps in the technical quality of CHV PNC practices, while also recognizing positive ele-
                                               ments of experiential quality of care, including communication quality, and trusting relationships. This study
                                               also demonstrated the strength of the CHVs’ role in establishing linkages between the community and facil-
                                               ities, as long as the CHV is perceived as, and enabled to be, an integral part of the PHC network in Kenya.
